I hate to ask this question because it's so tough to answer, but I need some opinions.
I'm an experienced IT systems admin/engineer with over 17 years years experience.  Certified with lots of hands on with Microsoft-based networks, VMware vSphere, and Citrix XenApp/XenDesktop/NetScaler (and more).  Went back to school (WGU) for a degree in cybersecurity just for fun and am almost finished.
I'm going to take the SANS Undergrad Certificate next.  It includes SEC401/GSEC. SEC504/GCIH, and then an elective.  And that's where I'm stuck.  Any thoughts on which course to take for an elective?
I'm not necessarily looking to move jobs when complete but I am trying to consider which elective course/cert might provide the most benefit in transitioning into a dedicated infosec role should I choose to.
Options are: SEC501/GCED, SEC503/GCIA, SEC542/GWAPT, SEC560/GPEN, FOR508/GCFA, and ICS410/GICSP.
My initial thought was GPEN since I have an interest (and I've also started to play with CTF's on the side), but also considering GCED.  Maybe I should be considering others as well?
These are probably the only SANS courses I'll ever get to take so I'm trying to make the right choice.
